I'm going to buy some chroma green paint tomorrow in the hardware store, so I can get the green bg.

My only issue is what to actually mount the product on - I need a large (maybe 15") plastic disc that I can paint chroma green & then place on the pedestal!
It needs to be light so the pedestal will still rotate with the weight (hence I assume it needs to be plastic), and it needs to be smooth so I can paint it and there won't be any blemishes or texture to it.
